PICKER-STICK.

Specification of Letters Patent.

Application led October 2, 1908. Serial No. 455,922.

To all whom it may concern:

Be it known that we, HENRY C'r, a citizen ofthe United States, residingat West Warren, county of Worcester, State of Masand RENCELER C. SNOW, acitizen of the United States, residing at W'are, county of Hampshire,and State of Massachusetts,

in Pickel'- Sticks, of which the following description, in connectionwith the accompanying drawing, isla specification, like characters onthe drawin representing` like parts.

i strain to which it may be his invention relates to picker sticks andhas for its object to provide a metal picker stick which Will be lightin weight and which will have suiiicient strength to withstand any ut.The novel features of theP invention will be more fully hereinafterdescribed and then pointed out in the a pendedl claims.

In the drawings igure 1 is a view of one end of a loom showing ourimproved picker on the line A stick of t Fig. 2; Fi

stick; Fig. 2 is a side view of the picker stick ;A Fig. 3 is a frontview thereof Fig. 4 is an enlarged section on the line x-x, Fig. 2;Fig.4 5 is an enlarged section on the line y-y, 6 is an enlarged`section ou the line lJr-a1., ig. 2; Fig. 7 is an enlarged section b-Fig. 2,- Fig. 8 is a view of a cast metal picker stick einb'odying ourinvention ,gltig 9 is an enlarged section on the line Referring to Fig:1, 3 is a portion of the loom frame', 4 is the lay, 5 the shuttle-box, 6the picker stick which is pivoted to thearm or bracket 7, and 8 is thelug stra which ernbraces the picker stick and whic transmits thelpicking motion thereto from the picking cam.

Picker sticks are now commonl Wood instead of metal, partly ecause awooden icker stick is lighter than a metal e same proportions, andpartly be'- ycause the wooden picker stick has certain necessaryresilient qualities which would be lacking 1n a metal picker stick ofthe saine shape. We have, however, designed a metal picker stick, theweight of which isnot appreciably greater than that of a wooden pickerstick and w 'ch has the necessary resilient ualities required in apicker stick. Our pic er stick is also strength than the ordinary pickerstick and is, t erefore, capable of out-wearing a Wooden icker stick.

In or er to make a picker stick `which is made of 'form the two of muchgreater light of Weight and yet has su'i'licient strength, we providethe body of the picker stick with a strengthening rib or flange whichextends longitudinally thereof and the depth of which is in a directionparallel to that in which the resistance of the shuttle is applied tothe picker stick. he necessaryresilient qualities ofthe picker stick areprovided for by making the upper end of the picker stick in the form oftwo separated and more or less resilient arms which arc adapted toreceive the picker.

The picker stick may be made of a piece oll wrought iron bent to theproper shape or may be made in the form of a casting. Then it is made of.wrought iron, we propose to usc a piece of strap iron of approximatelytwice the length of t 1e completed picker stick and to form the pickerstick by doubling the strap iron on itself and Welding or otherwiseconnecting thel two ends together and then twisting one of the sides ofthe doubled strap iron so as to cause it to stand at right angles to theother side. This gives the body of the picker stick either aT-shape oran L-shape in cross section. Such a picker stick is shown in Figs. 1-7inclusive, and it is formed from a piece of strap iron which is bent onitself to sides 9 and 10. The side 9 is substantially straightthroughout its length and the side 1() stands at right angles to theside 9, as clearly shown in Figs. 2, 8, 5 and 6, and may conveniently besituated centrali)Y 0f said sidey 9 therebygiving the body of the pickerstick a T-shape in cross section. This is not essential, however, as theside 1() migh t stand at one edge of the side 9, the essential featurebeing that itA stand at right angles to said side 9. The upper end ofthe two sides 9 and 10 is connected by a looped portion 11, one side 12of which may be a continuation of the side9, and the other side 18 ofwhich may be a continuation of the side 10. The two sides 12 and 13 ofthe loop stand one behind the other in the direction in which the pickermoves and in the direction in which the blow from the picker isdelivered to the shuttle. Said two sides or arms 12 and 13 constitutethe portion of the picker stick which receives the picker and owing totheir construction and position they make a properly resilienticker-receiving portion of the picker stick.

he picker 14 may be of any suitable or usual construction and may besecured to the upper end of the picker stick in any convenient way. Thetwo sides 9 and 10 are connected at their lower end by a looped portion1 5, the two sides 16 and 17 of which are preferably parallel with eachother and are continuations of the sides 9 and 10 of the body of thepicker stick. In making a pickerl stick of this sha ethe piece ofstrap-firon from which it is ma e is doubled on itse to form the twoloops 15and 11 and the ends of the pieces of strap iron are then weldedor otherwise connected together. Thereafter one of the sides, forinstance the side 10', is twistedl to stand at 'right an les withv theside 9, the twist in said side ta g place at the points 1 8 and 19,thereby forming the two closed loo s 11 and 15. lf desired bands 20 maybe placed around the two sides 9 and 10 to hold them in their properposition. The loop 15 a wooden block 21 which is provided. with thegroove or aperture 22 `to receive the pivotal to lthe bracket 7.' Theupper loop 11 re-A ceives the picker as above described. The loop 24 forthe reception of the lu strap 8 may be secured to the picker stiel: inany suitable way. We have shown, however, said picker stick as'providedwith two filling pieces 25 which are situated either'side of the web 10and which'form a' support to which the loop 24 may be secured in usualway.

picker stick made in this way is not appreciably heavier .than a,wooden. icker stlck, but is much stronger because o the relativepositions of the sides 9 and 10, the side 10 constituting a stilz'eningrib or web which runs longitudinally of the body of the picker stick.,The two sides 12 and 13 ofthe loop 11 which are embraced by the pickerare sufficiently resilient so that when the picker strikes the shuttlethe side 12 will yield and thus give to the picker stick the necessary'f resiliency. Instead ofV making ,the picker stick of wrought iron inthismanner, we may make it of castmetal, preferably of cast steel, asshown in Figs. 8 and 9. Apicker stick of this construction is made withthe body 9a which has cast integral therewith the stilening web 10a thatruns longitudinally thereof and stands at right angles ceiv'ing haspreferably placed therein pin 23 on which the picker is pivoted thereto.t the lower end the lpicker -stick is formed with the looped portion 15in to which awooden block similar tothe block 21 is inserted forfurnishing a bearing for' the picker stick on the pivotal pin 23. At theupper end the picker stick 1s cast'with the loop 11 a having the twosides 12a and 13, said loop 11a constituting [Lortion of the pickerstick. By making t e vis-gpm end of the picker stick in this way it havethe necessary ,resilient qualities, but will at the same time bestrengthened at the point where most strength is needed, without,however, giving to it an excessive weight. i

Having fully described our invention,

the picken-rewhat we claim as new and desire tosecure by y LettersPatent isz- 1. A (picker stick having provide which forms an integralpart thereof and ywhich is resilient in the direction inv which i ametal body the picker stick strikes its blow.

2. A picker stick having a metal bod A provided with a stiening ribextending. Ongitudinall thereof and end wit a looped picer-receivingportion.

3. A picker stick having a meta shape in cross section and `havin as an1ntegralpart thereof a resilient picli ing portion at lits u per end.

' 4. A picker stic having a metal body T- shape in cross section andhaving at its upper end a looped portion to receive the picker. 5. Ametal picker stick having a strengthening rib extending longitudinallythereof .and provided at its lower end with a loog and a wooden blockinserted in said loop an Y with a picker-receiving portion..v

er-rec'eivprovided with a bearing for the pivotal pin of the pickerstick. v

In testimony whereof, we have signed our namesvto this speciication, inthe presence of two subscribing witnesses.
